TABLE 



FOE CONVERTING MILLIMETEES INTO ENGLISH 

 INCHES AND DECIMALS. 



EXPLANATION. 



The table herewith, given shows the equivalents in Eng- 

 lish inches, and decimals thereof, of every tenth of a milli- 

 metre, from 1.0 to 100.9. From 100 to 1,000 millimetres 

 may be reduced to inches and decimals by multiplying the 

 corresponding figures of this table by ten ; that is, by mov- 

 ing the point in the column of inches one place to the 

 right. In a similar way, if multiplying by 100, move the 

 point two places to the right. For example : — 



(1) To reduce 72.7 millimetres to English inches : Find 

 in the vertical column to the left the figures 72; then 

 follow the horizontal line to the column headed .7. The 

 number found there (or, what would be sufficient for all 

 practical purposes, 2.86) is the equivalent of 72.7 millimetres 

 in English inches. 



(2) To reduce 605 millimetres to English inches, find 

 in the vertical column to the left 60, then follow the line 

 to the column headed .5, where will be found 2.3819 ; move 

 the point to the right, and you will have as the equivalent 

 of 605 millimetres 23.819 (or, what is essentially the same, 

 23.82) inches. 



(3) To reduce 1930 millimetres, find in the same way 

 the equivalent of 19.3, which is 0.7599 ; move the point two 

 places to the right, and 75.99 results, which expresses ex- 

 actly the equivalent of 1930 millimetres in English inches.
